On EDR simulated thermosiphon reboilers
Thread Content
When using EDR to simulate a thermal siphon reboiler, how should the pipe length term be calculated in the pipeline pressure loss calculation? Does it refer only to the length of the straight pipe section, or does it also include the length of fittings such as elbows (from the center of the elbow to its end)? For large pipes, the difference between the two is significant. Please give me some advice!
If I remember correctly, there is a siphon type in EDR, where you are required to enter details such as the exact length, the number of elbows, and the type of elbows
As I recall, the pipes in thermal siphons don’t have valves; there are only bends, tees, and things like that
With a valve added, it’s highly likely that thermal siphonning will no longer occur; the pressure drop that thermal siphonning overcomes is already very small, and by installing a valve and setting a certain opening degree, circulation may cease
